According to the source, ‘there is no way Moscow lets Warsaw walk away with such unfriendly actions’. There are several options considered in the Kremlin, such as personal sanctions against Polish officials who are involved in implementing the respective de-communization law in Poland and certain economic measures, which could result in worsening of Russia-Poland trade relations.
Some Russian politicians have been insisting that the government could, in turn, stop caring for Polish memorials in Russia, such as Katyn and Mednoe; thousands of captured Polish officers were executed there by the Soviets during WWII.
Currently, there are about 500 Soviet memorial sites across Poland; so far, it remains unclear how many of them fall under the de-communization law signed by Polish president Andrzej Duda. The document offers to demolish all memorials promoting Communism, except for those being parts of gravesites or military cemeteries.
